How many kilometers is the carbon deposit of the engine cleaned once, and how to clean the carbon deposit of the car

As the most common "chronic disease" of engines, carbon deposits exist in all parts of the engine. Of course, I believe that when you go to the 4S shop for maintenance, they have been recommended by the after-sales receptionist to clean the engine carbon deposits. Many friends who don't know much about cars may not know how often the carbon deposits in the engine should be cleaned, and how the carbon deposits are cleaned. So let's take everyone to find out.

How often does the engine carbon deposits be cleaned?

In fact, engine carbon deposits do not need to be cleaned frequently. Generally, cleaning once every 20,000 to 40,000 kilometers is considered a reasonable frequency.

Normally, we need to clean the engine carbon deposits only when the engine has idling jitter and other adverse reactions caused by carbon deposits. Of course, because under normal circumstances, the carbon deposits inside the engine have basically formed a certain degree of accumulation when the vehicle is traveling 20,000 to 40,000 kilometers, so if you don’t know the adverse reactions caused by the carbon deposits, you can use every 2 -The cleaning frequency of 40,000 kilometers is correct.

How to clean up carbon deposits in cars?

At present, the mainstream cleaning methods for engine carbon deposits include additive cleaning, bottle cleaning and disassembly cleaning.

Additive cleaning (fuel treasure):Additive cleaning is to directly fill the cleaning agent into the fuel tank and mix with the fuel. After the vehicle is started, the cleaning agent will enter the combustion chamber along with the fuel. When the cleaning agent enters the combustion chamber, it will affect the internal accumulation of the engine. The carbon undergoes a certain degree of cleaning.

Bottle cleaning:Bottle cleaning is what we usually call non-disassembly cleaning, which is also a cleaning method that is currently pushed by 4S shops. In this way, the cleaning agent is drawn into the combustion chamber of the engine along with the intake air flow through the form of a hanging bottle. In this process, the cleaning agent will clean the carbon deposits in the engine intake duct and the combustion chamber. .

Disassembly and cleaning:As the name implies, disassembly and cleaning is to remove the parts of the engine where carbon deposits are deposited for cleaning. Although this method has the best cleaning effect, due to the large workload, time-consuming and labor-intensive, generally 4S shops will not provide disassembly and washing services.
